The basics Chapter 1 DirectShow ConceptsFrom the viewpoint of the application programmer, Microsoft DirectShow is composed of two types ofclasses of objects: filters, the atomic entities of Direct

The next four chapters of this book deal with Microsoft DirectShow applications that capture media streams for manipulation by DirectShow. In most of the examples to follow, the streams will simply be

Of the three classes of Microsoft DirectShow filters—source, transform, and renderer—the source filter is the one that generates the stream data manipulated by the filter graph. Every filter graph has

Webcams have become nearly ubiquitous peripherals for today’s PCs. They’re inexpensive and produce video imagery of varying quality—often dependent on how much the webcam cost or how fast your compute

Although sample DirectShow filter graphs can be constructed and tested in GraphEdit, application programmers want to use standard programming languages—either C or C++—to construct DirectShow applicat

Chapter 2  GraphEdit因为本章只是GraphEdit的使用，没有什么高深的技术，所以就不一一翻译了。As you read Chapter 1, you might have visualized DirectShow filters as being boxes with input and output pins, connected with “wires,” on

Although many Microsoft DirectShow applications will benefit from the creation of a transform filter, transform filters can be difficult to test. Often, a programmer needs to construct a second filter
